Antibacterial Quantification from Lactic Acid Bacteria Isolated from Food Sources and Soil
Akharaiyi Fred Coolborn
Journal of Food Technology , 2013,
Abstract: Indicator bacteria of pathogenic and food spoilage capabilities were isolated from food sources, water and human feaces using MacConkey agar, Deoxycholate citrate agar and selenite F medium. Lactic Acid Bacteria (LAB) were isolated from soil, wine local cheese and corn slurry using MRS medium. Well-in-agar and paper disc methods were emplored for the antagonistic assay. The sensitivity of the indicator bacteria to LAB was indicated by clear zones of inhibition. Lactobacillus acidophilus exhibited the greatest inhibitory effect while Lactobacillus jugurti and Lactobacillus casei could not demonstrate visible inhibitory affinity on all the indicator bacteria. However, the LAB antagonistic activity over the indicator bacteria, displayed more elaborate inhibitory zones in the well -in-agar (5-6 mm) than the paper disc method (3-20 mm). Also the human enteropathogen assay with well-in-agar was between (2-26 mm) over (1- 8 mm) with the paper disc method.

Oyhakilome Gloria Irenosen, Aiyesanmi Ademola Festus, Akharaiyi Fred Coolborn
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.31003
Abstract: Composite water samples taken from Owena Multi-purpose Dam in six sampling campaigns covering the wet and dry seasons were analyzed for physico-chemical and microbial characteristics using standard methods for the examination of water and wastewater jointly published by the American Public Health Association, American Water Works Association and Water Pollution Control Federation. Results showed significant (p < 0.05) seasonal variations in most measured parameters with few showing significant spatial variation. The characteristics of the water from the dam lake revealed an acceptable quality for most measured parameters with low chemical pollutants burden when compared with drinking water standards and water quality for aquaculture. However, high values of turbidity, colour, iron, manganese and microbial load were recorded compared with drinking water standards, which call for proper treatment of the water before distribution for public consumption.

Advances in Bioscience and Biotechnology (ABB) , 2018, DOI: 10.4236/abb.2018.911039
Abstract: This study was carried out to investigate the antimicrobial activities of bacterial isolates of maize against plant pathogens as well as their growth responses to some environmental parameters. Twenty four bacterial isolates were obtained from maize plants collected from the Department of Biological Sciences, AfeBabalola University, Ado-Ekiti. The isolates were characterized by their biochemical and physiological characteristics and were identified as Kurthiazopfu, Morganellamorganic, Rhodococcusequi, Bacillus subtilis, Catabaterhongkongensis, Brevibacteriumotitidis, Lactobacillus coleohominis, Staphylococcus aureus, Propionibacterium acnes among others. Their responses to different NaCl concentrations, sugars, temperature as well as antibiotics were determined. Most of the isolates were able to withstand various environmental parameters in which they were subjected to. Also, eight isolates were able to ferment sucrose. The bacterial isolates showed a degree of resistance to the antibiotics tested. There was a high prevalence of multidrug resistant bacteria showing resistance to 3 - 8 drugs. The antagonistic effect of the bacterial isolates against selected fungi was determined. None of the isolates showed antagonistic potential against the fungal pathogens. However, the supposed antagonistic bacterial species can be genetically modified to produce secondary metabolites that will result in biocontrol.
ANTIBACTERIAL, PHYTOCHEMICAL AND ANTIOXIDANT PROPERTIES OF CNESTIS FERRUGINEA DC (CONNARACEAE) EXTRACTS
Fred Coolborn Akharaiyi,Bolatito Boboye,Adetuyi,F.C.
Journal of Microbiology, Biotechnology and Food Sciences , 2012,
Abstract: To evaluate the health relevance of decoctions, infusions and concoction of medicinal plants in traditional medicine, antibacterial efficacy of crude aqueous, ethanol and petroleum ether extracts of Cnestis ferruginea leaf, stem bark and roots were assayed against nine clinical bacterial isolates namely Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Bacillus cereus, Shigalla dysenteriae, Campylobacter jejunum, a -hemolytic group A streptococcus, and Salmonella enterica ser.Typhi by agar well diffusion method. The leaf extracts had higher inhibitory effects at various degrees than the stem bark and root extracts. Chemical methods were used to determine the quality and quantity of phytochemical components where alkaloids, flavonoids, saponin, tannins, phenol and cardinolides were found present. The antioxidant activities of the extracts of the plant tested were determined by a spectrophotometric method using the stable free radical DPPH (2, 2-diphenyl-1-picrylhydrazyl). Considerable antioxidant activities were found in the plant extracts. C. ferruginea contains bioactive principles necessary for bacteria inhibition and therefore, the powder could be used as preservative, beverage and source of novel drug(s).
Mixture of honey and ginger extract for antibacterial assessment on some clinical isolates.
OMOYA, F. O,AKHARAIYI, F. C.
International Journal of Pharmaceutical and Biological Research , 2011,
Abstract: The antibacterial activity of honey, methanol and ethanol extracts of ginger (Zingiber officinale) were investigated against some selected bacteria using the agar diffusion technique. Two Gram positive and four Gram negative bacteria were assessed for possible inhibition by the extract samples. The inhibitory potency of the extracts on the test organisms varied in the halos as inhibition effects. Though all the test organisms were susceptible to the antibacterial samples with inhibition measure between 6-3mm, E. coli was the most inhibited where an inhibitory measure of 20mm was recorded with honey, 18mm with ginger ethanol extract and 32mm with the mixture of honey and ginger ethanol extract. The pasture honey, the ethanol and methanol extracts of ginger were both positive for saponin and cardiac glycosides among the phytochemicals identified. While some of the commercial antibiotics (positive control) were not effective on the test organisms, gentamycin and streptomycin were effective with inhibitory halos ranging between 8-25mm. However, the antibacterial test samples were higher in inhibition values than the reference drugs (positive control).

Fred Bedell
Open Journal of Political Science (OJPS) , 2014, DOI: 10.4236/ojps.2014.43011
Abstract:
This essay speaks to government policies, the practices of the corporate sector, the inherited wealth of the few, and the consumptive behavior of the masses as the underlying causes of economic injustice. This is perceived as leading the country to an oligarchy.
Assessment of Wrap Sizes as it Affects Storage of Fufu, a Traditional Cassava Based Fermented Products
F.C. Akharaiyi,R.A.O. Gabriel
American Journal of Food Technology , 2007,
Abstract: Fufu, a traditional Cassava based fermented food product was prepared in the Laboratory and used for the study. Due to the short time storage and transportation of this particular food from one place to another on a popular demand because of its nutritional values, three wrap sizes were adopted to assess storage improvement. In this method, 50 g, 100 and 200 g of raw fufu were wrapped before cooking for the normal 1 h. The batches were stored on a wooden tray at ambient temperature in the laboratory. Quantitative determination of microbial and chemical changes occurring in the fufu samples was studied for four weeks. Microbial counts was higher in the 200 g wrap at fourth week of storage being 8.40x104 cfu (g-1) for bacteria and 2.32x103 spore (g-1) for fungi while it was 1.35x104 cfu (g-1); 1.06x103, 1.66x103 spore (g-1) bacterial and fungal counts, respectively for 50 g and 100 g wraps. Also at fourth week of storage pH was 3.80, 4.06 and 6.15; TTA was 0.45, 1.85 and 2.56% (W/W lactic acid) while moisture was 45.10, 58.40 and 70.30%, respectively for 50, 100 and 200 g wraps. In the pounded fufu at fourth week storage, colour odor, aroma and texture rating were significantly higher (p<0.05) for the 50 and 100 g wraps for overall acceptability while the 200 g wrap characters were very low thus unacceptable. This implies that smaller wrap sizes will store longer than big wrap sizes.

Branch Dynamics: A Theoretical Interpretation of Natural Phenomena  [PDF]
Fred Y. Ye
International Journal of Modern Nonlinear Theory and Application (IJMNTA) , 2013, DOI: 10.4236/ijmnta.2013.21A009
Abstract:
The mechanism of natural branching is explored, which is characterized by branch dynamics, where interior dynamics and exterior dynamics reveal the unified mechanism of physical and biological phenomena. While interior dynamics is characterized by gene-interaction, gene-interchange and gene-interpretation via the quaternion mathematical processes of Cayley-Dickson branching, Grassman branching and Euclidian branching, exterior dynamics is characterized by multi-vector physical unification. Everything in the world is linked by branches, and the dynamic mechanism of the branching phenomena is approached by branch dynamics.
